Influence of Atmospheric Rivers on Lake Ice Phenology in the Northern Hemisphere

Abstract Atmospheric rivers (ARs) can rapidly alter regional hydrothermal conditions and directly affect lake ice. This study presents the first assessment of AR impacts on lake ice phenology across the Northern Hemisphere. AR events were associated with positive anomalies in temperature, rainfall, and snowfall, as well as negative anomalies in solar radiation. These climate anomalies showed significant correlations with lake ice phenology. Between 1951 and 2022, AR‐associated climate anomalies
